Rosendale likes to tout itself as the Festival Town, committed to a packed agenda of public events celebrating everything from Beltane to pickles. But the granddaddy of them all – the one that put Rosendale on the map, festwise – is celebrating its 35th anniversary this year: the two-day, six-stage Rosendale Street Festival, which returns this Saturday and Sunday, July 20 and 21 with 73 bands participating at last count. Although in its earliest incarnation in the late ‘70s and ‘80s, the Festival strove to bring in national “name” acts, with mixed results (Tiny Tim turned out not to be a huge draw, if memory serves), the new, improved version – reinstated after a multi-year hiatus in the ‘90s – has an avowed mission “to help support and expose people to the local music of our region.”
